Access SARS-CoV-2 IgG II Assay, a semi-quantitative COVID-19 serology tool
Driving the path forward in the fight against COVID
By integrating a semi-quantitative SARS-CoV-2 antibody assay into the routine workflow, clinicians can establish a baseline to evaluate an individual’s adaptive immune response to the SARS-CoV-2 virus over time.

Another Assay in the COVID-19 Toolbox
Access SARS-CoV-2 IgG II is a semi-quantitative assay that measures a patient’s level of antibodies in response to a previous SARS-CoV-2 infection, providing a numerical result in arbitrary units (AU) from 2.00-450 AU/mL1 and a qualitative result reported as non-reactive (<10AU/mL) or reactive (>/=10AU/mL) to SARS-CoV-2.
With a semi-quantitative COVID-19 IgG antibody assay, clinicians can:
- Establish a baseline to evaluate an individual’s adaptive immune response based on a numerical value
- Assess an immune response to SARS-CoV-2 over time
Always, Quality First
The positive percent agreement (PPA) of the Access SARS-CoV-2 IgG II assay is 98.9% ≥ 15 days post symptom onset
The overall negative percent agreement (NPA) of the Access SARS-CoV-2 IgG II assay is 100%
High Specificity of 100% Minimizes Inaccurate Results
The Center for Disease Control (CDC) Recommends three strategies to improve positive predictive value3:
"Serological tests can play a critical role in the fight against COVID-19 by helping healthcare professionals to identify individuals who have overcome an infection in the past and have developed an immune response.4"

Deliver Results with Medical Value
This new assay offers the same level of quality as our other SARS-CoV-2 IgG and IgM serology tests. All of the Beckman Coulter COVID-19 antibody assays target the receptor-binding domain (RBD) of the spike protein (S1), as it is critical for viral entry.
Seamless Integration for Improved Lab Efficiency
- Integrate the assay seamlessly into your routine laboratory workflow
- Run in random-access-mode (RAM) without the need for batching or special maintenance
- Run up to 200 tests per hour depending on the analyzer used (for example, with DxI 800, labs can run up to 4,800 tests/day)
